The demand for images and video sequences inmedical field has increased drastically over the years. The needfor reducing the storage space has resulted in imagecompression. A new method of medical image compression hasbeen proposed to achieve high PSNR (Peak Signal to NoiseRatio) and CR (compression ratio). This paper presents animage compression algorithm which combines Haar waveletwith a linear approximation transform and SPIHT encoder.Experimental results are provided to demonstrate that theproposed approach is able to withstand a variety of imagecompression methods with high CR and PSNR.
